Abstract
PURPOSE:To prevent the level of a gate output from dropping by connecting MOS transistors (TRs) for separating an electric power source between a driving circuit and load MOS TRS and driving the driving circuit through MOS TRs inputting power voltage as a gate input. CONSTITUTION:MOS TRs 23, 24 for electric source separation are connected between a driving circuit consisting of MOS TRs 25-33 and load MOS TRs 21, 22 and the driving circuit is driven through the TRs 25, 26 inputting power voltage Vcc as a gate input. When an input IN is turned to a low level and the TR27 is turned off, a node P rises up to voltage Vcc because a node Q exceeds the voltage Vcc by the gate capacitance coupling of the TR23. The same is applied to a node S and, even if the TR for separating the electric power source is connected, gate outputs from push-pull TRs 31, 32 are prevented from level reduction, the working speed is increased and the operating margin of the electric power source is improved.
